To all whom it may concern:

Be it known'that I, MARGUERITE F. PonrEn, a citizen :of the United States, and a;

residentof the borough of Manhattan, city, county, and State 0 New York, have invented a new and useful Composition of Matter for Use as an Insecticide and Like Purposes; and in order that those skilled in' the art ma compound and use thesame I give the fo lowing specification thereof. My invention has for its object the productlon of an effective composition of matter for the destruction of insects of all kinds, including cockroaches, bedbugs and other insect ests which will not only be certain and re lable in its action, but which willbe non-inflammable and free from objectiom' able odor and, injurious-action upon articlesof furniture and parts of buildings and the like to which it is applied. In-carrying out my invention I. prepare a .composition of the followin ingredients, towit: gasolene, carbon tetrac lorld, terpineol and oil of cedar. The oil of cedar specified is preferably the oil of cedar leaf. These ingredients are mixed together in suitable proportions to form a uniform 'mixture. The terpineol employed has strong insecti cidal properties of 1tself, and in addition counteracts the penetrating and objectionable odor of the oil of ,cedar..

I have found the-followingproportions to Specification of Letters Patent. Application filed m 21, 1911; Serial No. 839,728. I

- Patented Dec. 5,v 1911.-

The difierent' oportions of the several, ingredients may' bevaried more or less as desired and are given by way of illustration and not as a limltation of the invention.

In preparing the composition I have found it preferable to first mix the gasolene with the oil of cedar, then to addthe terpineol to this mixture and lastly to add the carbon tetrachlorid. I

The composition is applied-in the usual ,way' to situations frequented by insects and is an effective agent for their destruction. Its insecticidal (properties are lastin and it .may be handle reason of. its noninflammable character and and stored with sa ety, by

its use is not attended with danger of poisoning to human life or-injurious effect on ,the parts of furniture or buildings where it is fitpplied. 1

aving described my invention, what I claim is: V 1. An insecticide, com rising. olene carbon tetrachlorid,- terpmeol an oil '0 cedar.

2. An insecticide,eomprising the following ingredients in substantially the pro ortions stated, to-wit: gasolene 2 pints, car on tetrachlorid 2 quarts 1 p' t, 3} gills terpineolgill-and oil of cedar gill;
